As far as I know, you still get the same benefits from a teabag as you do to loose leaf. Depending on the style of teabag, the teabag might actually soak up some of the important stuff in the tea, but it won't take all of it.

If you enjoy the convenience of the teabag at work then you should stick to what you enjoy.

As far as a good place to get loose white tea, I hear that silver needle is supposed to be pretty good stuff. Adagio has some and they even have it in teabags if you like. Most online vendors have some form of silver needle, it's pretty commonplace.

White tea is very fluffy and volumous (not dense). Because of this, you have to use a lot of leaf for every cup. Because of this, teaballs, bags, tea-spoons, etc. are not good for brewing white tea. If you can't get a teapot or brewing device with a built in way to keep the leaf in, then pouring from the pot through mesh should work fine.

My name is Kat. I just wanted to let you know that there is a white tea by "STERLING TEAS" that you can order online and have it delivered to you called "TROPICAL WHITE". It is a blend of white tea leaves such as pineapple, apple, orange, etc. Fruits and it smells and tastes wonderful.

I live in Rockwall, TX so I can just scoot over to the local Sterling Tea house to pick some up, but order some online and give it a try.

The LEAVES as opposed to tea bags, just seem to put out a better flavor overall.
